Reciprocating churn



UNITED STATES PATENT OFFICE;

JOHN DULY STOBAUGII, OF GRAYSON, MISSOURI.

RECIPROCATING CHURN.

EPECIFICATION forming part of Letters Patent No. 364,383, dated June 7, 1887.

Application filet'tFetrnary 28, 1857. Serial No. 228,557. (No model.)

To all whom it may concern:

Be it known that I, J OIIN DULY STOBA GH, a citizen of the United States, residing at Grayson, in the county of Clinton and State of Missouri, have invented certain new and useful Improvements in Reciprocating Ghurns; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings. and letters of reference marked thereon, which form a part of this specification.

Like letters refer to the same parts throughout the several views.

Figure 1 of the drawings is a perspective view of a churn constructed in accordance with myinvcntion. Fig. 2 is a central vertical section of the same.

This invention relates to that class of churns caller. reciprocating churns, and thenovelty consists in the peculiar means employed for reciprocating the dasher-stem, and in the poculiar combinations, arrangernenhand adaptation of parts, all as more fully hereinafter described,- shown in the drawings, and afterward specifically defined in the claim.

Referring now to the details of the drawings, A represents a churn-body of any approved construction.

B is the dfLShQPStGlll, to which are attached the dashers of any well-known construction.

To one side of the churn-body I hinge a platform designed to support the operating mech anism.

D is brace .or support for sustaining the weight of the platform and the operating mechanism. This brace is hinged at its lower end to the side of the churn-body, and when in position to support the platform its upper end may be retained in place by any suitable locking de'vice-such, for instance, as that shown in Fig. 2 of the drawings, in which I have shown a lug or casting secured to the under side of the platform, between the downwardlyextending ears of which the upper end of the brace is secured by means of a pin passed through a hole in said casting and a corresponding hole in the upper end of the brace, as will be readily understood. The hinging of the platform and of the brace allows of the tilting of'the platform when necessary to enable the operator to remove the dasher-steln and the contents of the churn. The end of the platform over the churn-body is cut away, as shown at a, and the upper portion bifurcated, as shown. This provides room for the cover and the dasher-stem, and when in position the cover of the churn is securely held in place.

Itigidly secured to the top of the platform is the yoke E, provided with legs 0, through which legs pass the means for securing the yoke to the platform. Substantially in the vertical center of this yoke is suitably journaled the main shaft F, provided with a suitable handle or crank.

G is a double drum or pulley secured on and turning with said main shaft, and H is a gearwheel fast on said shaft outside of the yoke.

I is anothershaft, journaled in said yoke and provided with a pinion, J, meshing with the gear-wheel H on the main shaft. This shaft I is also provided with a balance-Wheel, K,and upon its opposite end is secured a crank-disk, L, provided with a wrist-pin. c, to which is pivotally secured one end of the pitman M, the opposite end of which is provided with a pin, d, engaging a hole,e, in the flasher-stem. To guide the dasher-stem in its vertical movement, as well as to guide the pin (1, I provide the substantially semicircular'guard N,having extending therefrom at the top and bottom the arms a, by means of which it is secured to the platform and yoke, as shown. This guard is longitudinally slotted, as shown at f, and through this slot works the pin (1 of the pitman.

From the above description it will be readily seen that the rotation of the main shaft will, through the medium of the mechanism just described, impart a reciprocating motion to the dashcr-stem.

In order to render the device in a measure automatic, I secure to the double drum one end of two cords, so arranged that as one is Wound upon one drum the other cord is unwound from the other drum. To the free end of one of these cords I securea weight, P. By this means, when the main shaft is once turned to wind up one cord, the opposite cord is unwound. As soon as one cord is unwound the weight on this cord is detached, which can be readily done by means of the open hooks p, when the weight is put on the other cord,which will now run down. The weight is again detached and placed on the cord last wound up, and the operation repeated as long as it is desired to operate the churn.

When it is desired to get atthe interior of the churn, the brace is turned upon its hinges and the pin (Z of the pitman is disengaged from the hole in the dasher-stem and the slot in the guard, when the platform and its attached parts may be tipped back and 'thc dasher removed.

Having thus described my inventiomand set forth its merits, what I claim to be new, and desire to secure by Letters Patent, is

JOHN DULY STOBAUGH.
